October V- To f//fZ wlw/m. 'ii/2 may concern Be it known that .lh-rime MUELLER and ANTON C. SCHUERMANN, citizens of the United States, residing` at Decatur, in the county ol Macon and State of illinois, have invented new and useful improvements in Bubhler Heads, of which the following is a specification.

rllhis invention, which is a division of applicants` (1o-pending application, Serial No. 337,494, filed vNovember 12th, 1919, and which has been made the subject of a separate application under official requirement, relates to sanitary drinking fountains, and more particularly to improvements in the nozzle or bubbler head of such installations.

primarily, the invention has for its object, the provision of means for effectively permitting the discharge of water to issue from the drinking orifice in a heaped-up form, and with a constant and steady flow so that the danger of the lflow of water assuming the force of a jet is eliminated.

By reason of the particular formation of the nozzle or bubbler head, the circulation of water within the nozzle is such that the incoming water will. at all times force out the water previously delivered to the head of the nozzle, and thus prevent the stagnation of water within the head.

dditionally, the mouth of the nozzle is so formed as to cause the water to issue therefrom in a globular or spherical form without danger of splashing over the face of the user.

Referring to the drawings, wherein is set forth a prorerred embodiment of our invention:

Figure 1 is a vertical sectional view of the upper portion of a drinking fountain and pedestal with our improvement mounted thereon.

Figure 2 is a detailed sectional view of the nozzle or bubbler head.

Figure 8 is a bottom plan view of the bubbler head.

Figure 4 is a bottom plan View of the plate to which the bubbler head is secured.

1F igure 5 is a sectional view of the lower edge of the bubhler head showing the undercut groove for effecting engagement with the plate.

Referring to the drawings, wherein like 1919, Serial No,

Divided and this application filed -f 712.

numerals indicate like parts in the several views, 10 designates a pedestal, which, as is customary in such installations, houses the supply and waste pipes and their associated parts. the pedestal forms no part of the present invention, the upper portion only is shown. 11 designates a waste pipe, which is preferably traversed by the supply pipe 12. 1f desired, however, this construction may be varied to permit the supply pipe to enter the waste pipe at an angle thereto. The bowl 13 of the drinking fountain is supported on the pedestal 10, and together with the strainer is secured to the waste connection '15 by the screws 16.

The waste pipe 11 has secured thereto the coupling nut 17, having a iiange 18 provided with threaded openings, which receive the set screws 19, the set screws being tightened downwardly onto a plate 2O resting upon the lugs 21 integral with the pedestal 10.

Si nipple 252, having an enlarged threaded recess 25% adapted to receive the upper end or' the supply pipe 12 extends tiirough a centrally disposed sleeve of the strainer 14:. The upper end of the nipple 22 is provided with a reduced shoulder portion 25, which supports the plate 26. The l cap 27 has an internally thr laded opening 2d which engages the threaded end of the portion 25 of the nipple 22 so as to maintain the plate 2G in position. rlChe side or yiindrical wall of the baille cap 27 is provided with a plurality of openings or slots 29, through which the water discharges laterally.7 into the nozzle or bnbbler head 30.

The plate 26 adjacent its outer periphery has a depending flange 31, and extending laterally from the plate is a plurality of integral lugs 32, four of such lugs being shown inthe present instance. The plate 26 has a through aperture 33 to permit drainage from the bubbler head and preferably this aperture is open at all times so as to insure against stagnation of water in the lower part of the head.

The nozzle or bubbler head 30 is preferably circular in cross section and intermediate the ends of the head it is of restricted diameter. rEhe wall of the nozzle is gracefully curved inwardly at its upper end and terminates in a drinking orifice 34 circular in cross section. The outer edge about the opening or orifice 84 is hevelled as at 'so as to eliminate sharp edges, and assist the drinking huhhler in assuming a glohular or spherical form. The open lower end of the nozzle flares outwardly and is provided with an internal circumferential `groove 36, below which projects the spaced rib 3T, as shown in Figure 3. Vertical slots 38 formed in the bottoni ot' the nozzle 30 are equal in number and spaced apart similarly to the lugs 32 on the plate 2G so as to receive the saine. rllre plato 26 is moved inwardly of the nozzle 30 until the lugs 32 lie in the groove 3G, whereupon the nozzle is given a partial rotation so that the lugs rest against the rib 37. rllhe groove is then filled with a suitable cementitious material.

As heretofore stated, the nozzle 30 at its central portion is ot reduced or restricted diameter, as at 39, and the chainher Ll() below this reduced portion tlares downwardly and outwardly. The internal walls of the chamber Lll above the restricted portion 39 iiare upwardly and outwardly and then curve inwardly and slope upwardly until they terminate in 'the drinking oriiice 34. By reason of this construction, the water issues through the slots 29 ot the baille cap into the enlarged chamber l0, and due to the restrict-ed portion 39, the water is con ducted into the upper chamber #ll at increased velocity. The vater, upon reachingI the upper chamber will spread outwardly until it meets the upwardly and inwardly inclined walls of this chamber, which di` rect the water to flow towards the drinking orifice. Due to the inwardly inclined walls of the chamber 4l, the water issues 'from the drinking` orifice in cross currents, and at an angle to the axis of the opening: Sil so that the result is that the drinking huhhlc aslruines a globular or spherical torin.- The water issues 'from the drinking orifice without violence so that anyone may drink therefrom with ease and comfort.

It is to he understood that our invention is susceptible to various changes and modilications without departingv troni the spirit thereof and the scope ot the appended claims.

vWe claim:

l, -ln combination, a hubhler head having an internal ci ouinterentiaA groove, an interrupted rih below said groove, a supply pipe extendingl throu'fih the lower end ot said huhhler head, a plate having),- a drainage ojeninpY mounted on said pipe, and radially projecting lugs on said plate adaif ted to ei.- gage the groove in said huhhler head.

ln combination, hubhlcr liead an internal circuin'lie itial groove. terrugted rib below said groove, a pipe extending through the lower end 'i' said huhbler head, a plate hav a depending' tlange adjacent its outer periphery, radially extending` lugs on said plate adapted to engage the groove on said huhhlcr head, and means permitting` drainage tlow through said plate.

53. ln combination, a hulihler head having; an internal circunrtcrencial groove, an intr-rruptcd rib lielow said groove, a supply pipe extendingv through the lower end if said huhhler head, a plate having` a drainage opening` mounted on said pipe, radiali projecting` lugs on said plate adapted to en fgagze the groove in said huhloler head, .1 t halllc cap secured to said pipe ha ,y end closed and its side walls provid-:fd imtlet openings.
